What is the purpose of using inheritance-based polymorphism in C#?
To create a hierarchy of classes where derived classes inherit behavior and properties from a base class, allowing code to work with multiple types of objects without knowing the specific type at compile time.
To write code that only works with one specific type of object at compile time.
To prevent derived classes from inheriting behavior and properties from a base class.
What is the main advantage of using interface-based polymorphism over inheritance-based polymorphism?
It promotes code reuse by sharing common behavior across multiple classes.
It establishes a clear hierarchical relationship between classes.
It promotes loose coupling, enhances flexibility, and simplifies maintenance.
What is the main purpose of implementing polymorphism in a C# application?
To reduce the amount of code written.
To allow objects of different types to be treated as objects of a common base type.
To increase the complexity of the code.
What is the main disadvantage of using sealed classes and methods when implementing inheritance-based polymorphism in C#?
Sealed classes and methods can't be inherited or overridden, which limits the ability to use polymorphism.
Sealed classes and methods increase the flexibility and extensibility of the code.
Sealed classes and methods can be easily overridden, which can lead to confusion.
What is the purpose of casting in the context of inheritance-based polymorphism in C#?
Casting is used to change the value of an object.
Casting is used to convert an object of a derived class to another derived class.
Casting is used to convert an object of one type to another type, often when implementing polymorphism using inheritance hierarchies.
In which scenario would inheritance-based polymorphism be more appropriate than interface-based polymorphism?
When the developer needs to reduce code dependencies.
When the developer needs to establish a hierarchical relationship between classes and promote code reuse.
When the developer needs to decouple class dependencies.
